2. Write controller

The login method and ulogin method

under the controller package IndexController class

package cn.pangpython.controller;
  
import com.jfinal.aop.Before;
import com.jfinal.core.Controller;
import com.jfinal.ext.kit.SessionIdKit;
  
import cn.pangpython.model.User;
import cn.pangpython.utils.DateUtils;
import cn.pangpython.utils.MD5;
import cn.pangpython.validate.RegistValidator;
import cn.pangpython.validate.UserLoginValidator;
  
/**
 * @author pangPython
 * 主页控制器
 */
public class IndexController extends Controller {
    public void index(){
        renderText("index");
    }
  
    //渲染注册页面
    public void regpage(){
        render("regist.html");
    }
  
    //处理注册
    @Before(RegistValidator.class)
    public void regist(){
        String pwd = getPara("user.pwd");
        String confirm = getPara("reg.confirm");
  
        //验证码验证
        boolean result = validateCaptcha("reg.yzm");
        if(!result){
            setAttr("yzmErrMsg", "验证码错误！");
            render("regist.html");
            return;
        }
        //确认密码验证
        if(!pwd.equals(confirm)){
            setAttr("confirmErrMsg", "请正确填写确认密码！");
            render("regist.html");
            return;
        }
  
        String uname = getPara("user.name");
        User user = getModel(User.class);
        String reg_time = DateUtils.dateToUnixTimestamp(DateUtils.getNowTime())+"";
        //使用用户注册日期作为md5密码加密的盐值,可节省一个salt数据库字段
        pwd = MD5.GetMD5Code(pwd+reg_time);
  
        //给user实体类填充数据
        user.setName(uname);
        user.setPwd(pwd);
        user.setRegTime(reg_time);
  
        //使用jfinal的保存操作
        user.save();
  
        renderText("注册成功！");
    }
  
    public void login(){
        render("login.html");
    }
  
    @Before(UserLoginValidator.class)
    public void ulogin(){
        // 验证码结果
        boolean result = validateCaptcha("yzm");
        if (!result) {
            setAttr("yzmErrMsg", "验证码错误！");
            render("login.html");
            return;
        }
  
        String uname = getPara("user.name");
        String sql = "select * from user where name = ? limit 1";
  
        User user = User.dao.findFirst(sql, uname);
        if (user != null) {
            String pwd = MD5.GetMD5Code(getPara("user.pwd") + user.getRegTime());
  
            if (user.getPwd().equals(pwd)) {
  
                // 生成唯一标识
                String sessionId = SessionIdKit.me().generate(getRequest());
                // 设置服务器端session
                setSessionAttr(sessionId, user);
                // 设置用户端cookie
                setCookie("cuser", sessionId, 60000);
                //redirect("/user");
                renderText("登录成功！");
  
            } else {
                // 密码不正确
                setAttr("UnameErrMsg", "用户名或密码不正确！");
                render("login.html");
            }
  
        } else {
            // 用户名不存在
            setAttr("UnameErrMsg", "用户名不存在！");
            render("login.html");
        }
  
    }
  
}

3. Write login validator

UserLoginValidator under the validator package inherits JFinal’s Validator

import com.jfinal.core.Controller;
import com.jfinal.validate.Validator;
  
public class UserLoginValidator extends Validator {
  
    @Override
    protected void handleError(Controller controller) {
        controller.keepPara();
  
    }
  
    @Override
    protected void validate(Controller arg0) {
        validateRequired("user.name", "UnameErrMsg", "请输入用户名！");
        validateRequired("user.pwd", "PwdErrMsg", "请输入密码！");
        validateRequired("yzm", "yzmErrMsg", "请输入验证码！");
    }
  
}
